Do Infants Grow Out of Colic?

If your baby cries endlessly and nothing seems to help, you're not alone. Many parents are told, "Don't worry, they'll grow out of it," but that advice often misses something deeper. Babies don’t just grow out of colic. They grow into other challenges.

The constant crying, the arching back, the sleepless nights that leave you second-guessing everything—these are not just tough phases. They’re your baby’s way of telling you something is off in their nervous system.

The Truth About What Happens After Colic

Every week, families walk into clinics with children who now struggle with sensory issues, ADHD, or anxiety. When their histories are reviewed, many of those children were colicky babies. The same nervous system stress that caused nonstop crying as infants is now showing up as emotional and behavioral struggles.

You’re not imagining the connection. And you’re definitely not failing as a parent.

Why Everything You’ve Tried Hasn’t Worked

If you’re reading this, you’ve probably tried it all. You’ve cut dairy, switched formulas, kept food journals, tried gas drops, probiotics, and sleep routines. You’ve done everything “right,” yet the crying continues.

You’re not missing something as a parent. You’re just missing the piece that most people never talk about.

The Real Root Cause Goes Deeper Than Digestion

Most people believe colic is all about digestion—gas, food sensitivities, or reflux. While those symptoms are real, they’re only part of the story. The digestive system is controlled by the nervous system.

Think of your baby’s nervous system as their internal control center. When that system is under stress, it can throw off everything—digestion, sleep, development, and mood. The vagus nerve, which runs from the brainstem down through the body, helps regulate digestion and calming responses. When this nerve or the upper neck area is stressed during birth, digestion and regulation can literally get stuck.

So rather than a baby who will “grow out of it,” what you really have is a baby whose nervous system is stuck.

• Stuck in stress from birth
• Stuck in tension in the neck and back
• Stuck in distress that shows up as colic

The Hidden Trigger No One Talks About: Birth Trauma

Nearly every colicky baby has experienced some form of birth intervention—C-section, vacuum, forceps, or induction. These are sometimes necessary, but they also create stress and tension in the upper neck where critical nerves live.

That tension can start even before birth. If you were stressed during pregnancy, your baby’s developing nervous system felt it too. The umbilical cord transfers those stress hormones directly.

When the upper neck and mid-back are tight, babies arch their backs and cry because they’re literally trying to stretch out the tension. Your baby isn’t being “fussy.” They’re communicating through their body language that something doesn’t feel right.

The Progression Parents Should Know

When nervous system stress isn’t addressed, here’s what often happens:

• 0–6 months: Colic, reflux, and poor sleep
• 6–18 months: Chronic ear infections
• 18–36 months: Speech delays
• 3–5 years: Sensory challenges
• 5–10 years: ADHD or anxiety

The same stuck stress pattern simply evolves as your child grows. The colic doesn’t go away- it just changes form.

And when antibiotics or medications are added for recurring infections, gut health and the nervous system can become even more imbalanced. It’s like trying to drive with the parking brake still on.

What Your Baby’s Body Language Is Saying

When your baby arches their back or cries inconsolably, they’re not just uncomfortable- they’re trying to release tension. Just like you might stretch after sitting too long, your baby is instinctively trying to unwind stress in their spine and nervous system.

Colic is not something you need to “wait out.” It’s your baby’s signal that they need help calming and regulating their nervous system.

The earlier this is addressed, the easier it is for the body to heal because of the brain’s amazing ability to form new connections in infancy.

What Parents Can Do

Trust your instincts. You know your baby better than anyone else. If something feels off, keep searching for answers.

Steps You Can Take:

• Look for practitioners who understand the nervous system. Seek those who treat the whole child, not just the symptoms.
• Reflect on your birth story. Were there interventions or stress during pregnancy? That may offer clues.
• Document patterns. Track your baby’s behaviors, what helps, and what makes things worse. Share that with your provider.
• Think long-term. Focus on healing the cause, not just managing symptoms.

Your Baby Deserves More Than “They’ll Grow Out of It”

Your child doesn’t need another label or a lifetime of symptom management. They need relief from the stuck stress in their nervous system.

When that tension is released, parents often see incredible changes. Babies who once cried for hours become calm and content. Sleep improves. Digestion settles. The whole family begins to breathe again.
